Abstract
The present application relates to a polyester and the molded product thereof. Determined by aminolytic analysis, the polyester has a weight ratio of the second repeating unit of formula (ii) to the third repeating unit of formula (iii) is of 0.100 to 0.490 as determined by analysis of the polyester. The polyester of this application has ideal dyeing ability, heat resistance, and mechanical properties.
Claims14
A polyester, comprising:
- a first repeating unit represented by formula (i):
- wherein R1 is a C6-C16 aryl group;
- and
- repeating units derived from a diol, wherein the repeating units derived from the diol comprise a second repeating unit, a third repeating unit, and an aliphatic cyclic alcohol residue, wherein the second repeating unit and the third repeating unit are represented by formulae (ii) and (iii) respectively:
- wherein * represents a linking bond;
- wherein a weight ratio of the second repeating unit to the third repeating unit is of 0.100 to 0.490 as determined by aminolytic analysis of the polyester.
